Zero Raspberry Pi Gpio Pinout

Pins 1 2 39 40 are also labeled below click here for hi resolution image.

Zero raspberry pi gpio pinout. Running pinout on its own will output a board diagram and gpio header diagram for the current raspberry pi. Support pinout xyz on patreon. The mcp3424 is a delta sigma a d converter with low noise differential inputs. The io pi zero is a 16 channel digital expansion board designed for use on the raspberry pi zero.

The io pi zero expander is powered through the host raspberry pi using the gpio port and extended pins on the gpio connector allow you to stack the io pi zero. Every pi model since the raspberry pi b has had 40 gpio pins though on the pi zero and zero w you have 40 holes that. Raspberry pi gpio pinout. The servo pwm pi zero is a 16 channel 12 bit pwm controller for the raspberry pi suitable for driving leds and radio control servos.

It also includes dozens of pinouts for raspberry pi add on boards hats and phats. What each pin does on pi 4 earlier models. Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes. Servo pwm pi zero.

The comprehensive gpio pinout guide for the raspberry pi. This gpio pinout is designed to be both a quick and interactive reference to the raspberry pi gpio pins plus a comprehensive guide to your raspberry pi s gpio interfaces. The adc pi zero is based on two microchip mcp3424 a d converters each containing 4 analogue inputs. A utility for querying raspberry pi gpio pin out information.

The board is based around pca9685 pwm i2c led controller ic from nxt and can drive each of the 16 outputs with 12 bit 4096 steps duty cycle from 0 to 100. The board is based around the mcp23017 16 bit i o expander from microchip technology inc. It is also possible to manually specify a revision of pi or by configuring remote gpio to output information about a remote pi. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w.

The raspberry pi zero w board contains a single 40 pin expansion header labeled as j8 providing access to 28 gpio pins. The board includes power on and battery low indicator leds as well as a jst connector to which you can connect a lipo liion or other battery with a jst plug. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header.
